This approach won't actually work as HeaderReceived IRQ can only be detected via interrupt on I remember seeing from the recommended design document that it is recommended to connect at least dio0..dio3 to your MCU. |
Also dropped one additional debug message about HeaderValid flag.

With sx127x there is no single "IRQ detected" pin for MCU, instead it has six different DIO pins which all have varying roles.
In order to get preamble detection working (and to be able to join LoRaWAN network) make sure DIO3/ValidHeader IRQ are configured.
